* Takes one or more tracks as input; of all the WaveTracs,
* it mixes together all input tracks, applying any envelopes, per-track
* real-time effects, volume, panning and real-time effects in the process. The
* resulting pair of tracks (stereo) are "rendered" and have no effects, volume,
* panning, or envelopes. Other sorts of tracks are ignored. If the start and
* end times passed are the same this is taken as meaning no explicit time range
* to process, and the whole occupied length of the input tracks is processed.
*
* Channel group properties of the result are copied from the first input track,
* except that `newTrackName` is applied when more than one track is mixed.
*
* @param newTrackName used only when there is more than one input track (one
* mono channel or a stereo pair); else the unique track's name is copied
